Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552162, here are decompositions:

23 + 31552139 = 31552162
113 + 31552049 = 31552162
359 + 31551803 = 31552162
479 + 31551683 = 31552162
491 + 31551671 = 31552162
563 + 31551599 = 31552162
569 + 31551593 = 31552162
659 + 31551503 = 31552162

Showing the first eight; more decompositions exist.
